Schlage 09-634L 626 L583-363 – Frequently Asked Questions

1) What does "thumbturn x blank" mean on the Schlage 09-634L?
You get a thumbturn on one face of the door and a plain blank escutcheon on the other. So the door can be locked and unlocked from the inside only, with no keyway, lever, or turn on the opposite face. That is the arrangement used on restrooms, storage, and similar interior openings where one-sided control is what you want. If you need key access from the outside, this is the wrong trim.
2) Is this Schlage thumbturn trim ADA compliant for a healthcare or school restroom?
The 09-634L uses a large ADA thumbturn, described as meeting accessibility requirements for interior door applications so it can be operated without tight grasping or pinching. That is the reason it gets specified in healthcare, education, and government interiors running L Series hardware. If your accessibility reviewer wants a lever-operated privacy turn instead, the large thumbturn is still the accessible option within this trim family.
3) Do I get a complete lock with this, or just the escutcheon trim?
Trim only. The 09-634L is a replacement escutcheon with the thumbturn, catalogued as a replacement part for commercial use. The mortise lock case, latch, strike, and any lever or knob on the opening are separate. Order it when the lock body is sound and the trim is damaged, worn, being refinished, or being converted to an accessible thumbturn.
4) Can a Schlage Electronics 47260707 CO Series escutcheon be used in place of the 09-634L L583-363 thumbturn escutcheon?
No. The Schlage 09-634L L583-363 is a mechanical thumbturn x blank L escutcheon with a large ADA thumbturn, made as a replacement trim part for Schlage L Series interior mortise lock applications. The Schlage Electronics 47260707 is a CO Series exterior escutcheon for cylindrical and mortise locks on the CO100 platform, and it is a keypad unit supplied with fasteners and an O-ring. One gives you manual thumbturn operation on an L Series mortise body; the other gives you keypad credential entry on the CO Series platform. They are not interchangeable trim, and the CO escutcheon will not mount to an L Series mortise lock prepped for the 09-634L.
5) Is the Schlage CO Series escutcheon a substitute for the 09-634L?
No, they solve different problems. The Schlage Electronics 47260707 CO Series exterior escutcheon is a keypad trim for CO100 cylindrical and mortise locks, and the 47260708 is the keypad exit-trim escutcheon in aged bronze. Both are electronic access-control faces. The 09-634L is mechanical trim with a thumbturn for an L Series mortise lock and carries no credential reader.
6) Which finishes does the Schlage 09-634L thumbturn escutcheon come in?
Eight finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 625 bright chrome, 626 satin chrome, 629 bright stainless steel, and 630 satin stainless steel. If you are patching one opening in a building already standardized on L Series trim, match the BHMA number stamped or specified on the existing escutcheons rather than guessing by eye, since 605/625 (bright) and 606/626 (satin) read very differently side by side.
7) Can I use this Schlage escutcheon on an exterior door?
No. The 09-634L is specified for L Series interior applications, and the blank plate on one face gives no outside access at all. For an exterior opening you want a keyed trim on the outside face, not a blank.
8) Will this thumbturn escutcheon match the other L Series doors in my building?
It is genuine Schlage L Series trim in the large L escutcheon format, so the plate shape and proportions line up with the rest of your L Series openings. Pick the finish code that matches what is already installed and the replacement reads as original rather than a patch.
9) I need an escutcheon in aged bronze - is the Schlage Electronics 47260708 the same part in a different finish?
It is a different part entirely. The Schlage Electronics 47260708 is a CO Series exterior escutcheon for exit trim on the CO-100 platform, a keypad unit offered in aged bronze. The Schlage 09-634L L583-363 is a mechanical thumbturn x blank L escutcheon for L Series interior mortise locks, and its finish choices are the standard architectural codes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 625 bright chrome, 626 satin chrome, 629 bright stainless steel and 630 satin stainless steel. If the goal is a dark bronze appearance on an L Series interior opening, 613 oil rubbed bronze or 612 satin bronze is the direction to take, not the CO Series exit trim escutcheon.
10) Will an MS Sedco ESC stainless escutcheon plate work as a cover plate on an L Series mortise door?
No. The MS Sedco ESC is a decorative stainless escutcheon plate made for MS Sedco R4 and R6 round switches, so it is trim for a push-switch actuator, not for a lock body. The Schlage 09-634L L583-363 is a thumbturn x blank L escutcheon built for Schlage L Series interior mortise lock applications, with a large ADA thumbturn on one side and a blank plate on the other. If the opening has an L Series mortise lock and you need the blank side covered, the 09-634L already provides that blank face as part of the pair; the Sedco plate has no lock prep and will not cover an L Series mortise cutout.
